Registered Replication Report: Dijksterhuis and van Knippenberg (1998)
Dijksterhuis and van Knippenberg (1998) reported that participants primed with a category associated with intelligence ("professor") subsequently performed 13% better on a trivia test than participants primed with a category associated with a lack of intelligence ("soccer hooligans"). In two unpublished replications of this study designed to verify the appropriate testing procedures, Dijksterhuis, van Knippenberg, and Holland observed a smaller difference between conditions (2%-3%) as well as a gender difference: Men showed the effect (9.3% and 7.6%), but women did not (0.3% and -0.3%). The procedure used in those replications served as the basis for this multilab Registered Replication Report. A total of 40 laboratories collected data for this project, and 23 of these laboratories met all inclusion criteria. Here we report the meta-analytic results for those 23 direct replications (total N = 4,493), which tested whether performance on a 30-item general-knowledge trivia task differed between these two priming conditions (results of supplementary analyses of the data from all 40 labs, N = 6,454, are also reported). We observed no overall difference in trivia performance between participants primed with the "professor" category and those primed with the "hooligan" category (0.14%) and no moderation by gender

The Social Network of Solidarity With Migrants: The role of perceived injunctive norms on intergroup helping behaviors
Using an egoâcentered network approach, we examine across two studies whether and how injunctive network norm sâbehaviors that are approved by altersâare related to majority membersâ decisions to participate in helping actions supporting migrants. We hypothesize that the more people perceive their personal social networks as positive toward humanitarian actions for migrants, the more they consider their opinions on migration issues as selfâdefining, and the more they are willing to mobilize in helping behaviors. With a name generator approach, we collected personal social network data among majority members of Belgian, mobilized volunteers (Study 1, N =204) and Swiss, nonâmobilized participants (Study 2, N =247). Results demonstrate the impact of injunctive network norms in promoting and maintaining helping actions for migrants, and the role of selfâdefining attitudes. Overall, the results highlight the importance of injunctive norms within personal social networks on participation in intergroup helping behaviors.info:eu-repo/semantics/publishe
